Sweetgrass Repels Mosquitoes

New information about the chemicals (coumarin and phytol) in sweet grass, Hierochloa odorata, confirm that they may repel mosquitoes. Native Americans knew this all along and have used sweet grass for many ceremonies.  Sweetgrass is a native plant in Minnesota; flowers come in early spring and the shiny foliage is not really ornamental, but that doesn’t matter, when the fragrance and other chemicals in the foliage are what is important.
